I want to make an enumerated list in the following format:
[1] foo foo
[2] foo foo
...
How I can do that using enumerated lists? I have tried the following:
\begin{enumerate}[\left[ 1 \right]]
but it does not work.
TeX - LaTeX Stack Exchange is a question and answer site for users of TeX, LaTeX, ConTeXt, and related typesetting systems. It only takes a minute to sign up.

package to format the enumerated list:
\documentclass{article}
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\begin{document}
\begin{enumerate}[label={[\arabic*]}]
\item First item
\item Second item
\item \ldots
\item Last item
\end{enumerate}
\end{document}
Note that you are required to encase the optional argument in braces {
...}
since it contains square brackets; used in general for optional arguments and would otherwise "confuse" LaTeX.
If you want to make a global setting to your list (rather than the optional argument on a per-list basis), you can use
\setenumerate[1]{label={[\arabic*]}} % Global setting
or you could make your own list using
\newlist{mylist}{enumerate}{1}%
\setlist[mylist]{label={[\arabic*]}}%
which would allow you to use
\begin{mylist}
...
\end{mylist}
The enumerate Package wants you to put those brackets into a group
\documentclass{article}
\usepackage{enumerate}
\begin{document}
\begin{enumerate}[ {[}1{]} ]
\item first
\item second
\end{enumerate}
\end{document}
For the sake of completeness, if you want to change the list format without loading any packages, you can redefine \labelenumi
as:
\renewcommand*\labelenumi{[\theenumi]}
For deeper levels, just change the counter, i.e, i
, ii
, iii
.
You might use in a local scope, otherwise this change will be reflected globally:
\documentclass{article}
% global change
\renewcommand*\labelenumi{[\theenumi]}
\begin{document}
\begin{enumerate}
\item Juventus
\item Milan
\item Udinese
\end{enumerate}
\end{document}
To use it locally, you might try:
\begin{enumerate}
\renewcommand*\labelenumi{[\theenumi]}
\item Juventus % [1] Juventus
\item Milan % [2] Milan
\item Udinese % [3] Udinese
\end{enumerate}
\begin{enumerate}
\item Juventus % 1. Juventus
\item Milan % 2. Milan
\item Udinese % 3. Udinese
\end{enumerate}
Again, don't do this, use a package instead. I'd go with either enumitem
or enumerate
. :)
\begin{enumerate}
\item[{[1]}] First statement
\item[{[2]}] Second statement
.
.
.
.
\left[...\right]
construct, but note that you need to be in math mode to use that so you can use the solutions below with[label={$\left[\arabic*\right]$}]
.
